When you add the degrees of all the angles in a triangle you should get 180

A= 5x+5
B= 90
C= 3x+5

5x + 3x = 8x
5 + 90 + 5 = 100

8x + 100 = 180 this is the equation
-100 -100
————————
8x = 80 ➡️ divide BOTH sides by 8

x = 10

Now plug 10 into angles A and C

5(10)+5= 55
3(10)+5= 35

A= 55 , B= 90 , C=35

How do you find the volume of a triangular prism with different bases formula
Debora [2.8K]

Answer:

Triangular prisms

Remember the formula for calculating volume is: Volume = Area by height. V = A X h.

For a triangle the area is calculated using the formula: Area = half of base by altitude. A = 0.5 X b X a.

So to calculate the volume of a triangular prism, the formula is: V = 0.5 X b X a X h.
